Al Kossow did tremendous work on some MiniFrame tapes:

BO-11X-4 Tape Files

Files.txt

Al shared an email on August 26, 2014:

About a month ago, I found a box of CTIX labeled carts at a flea market.

Sadly, I went through them today and all but one of them has been written

over with accounting backups.

I was able to save the first few files from a single user system tape

which I've attached. There is a read error at the start of the CPIO of

the root file system (file 8). There are some stand-alone utilities though

which may be of use.

I'm going to scan all of the labels just so there is a record of what

they look like.

This was all very frustrating since I spent a bunch of effort over the

past month trying to make sure that I would recover as much as I could

assuming they would be good for only one read pass.

August 27, 2014:

OK, some slightly better news..

I worked on the tape again today, and was able to recover all but 11 blocks

I've put what I recovered up under

http://bitsavers.org/bits/Convergent/miniframe

it will take a couple hours for the mirrors to pick it up

The bad blocks are in CPIO archives, so it is possible to stitch the pieces back together

Interestingly, the C compiler and header files are on there.

Here are the labels from the tapes that Al Kossow was unable to image, because tapes were "written over with accounting backups."
